MACHINE non To all whom it may concern:

Be it known that LOscan A. SMITH, a citizen of the United States, residing in- Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in- Machincs for Castellating Nuts, of which the following is a specification.

This invention relates to machines for antomatically forming a'inumber of diametralslots: in nuts or the like, sometimes termed castellated nuts for the purpose of being engaged by cotter pins to lock thenuts' in position and prevent their becoming loose orcominbftii T .The ob ect 'of the invention is to provide a machine of" this character that wlll be en-' tirely. automaticin-its operation, the nuts simply being placed in a. -ho per, from In the accompanying drawings represent- 1 shows the machine in. end elevationl ig. 2 is a side elevation of the machine, certain parts being broken. to show the interior construction. Fig. 3 is a section enlarged 4 is a fragmentary view enlarged showin the three cutters.- and Fig; 5 shows one 0 On a suitable frame F is a casing 6.in which rotates a head 7. In one face of the head-is a circular series of sockets, these shown separately in Fig.6, which bushingl is-shown as having a socket portion 9v of t e proper shape to receive the nut, which isshown hexagonalffor re er-. ably of slightl less depth than the eight orthickness 0 the nut, so that the saw or turret will not engage the face of the bushmg.

Any of the usual or preferred means for indexing the head used in turret lathes and automatic machines may be employed, by

an an gular'distanoe' e ual to the angular dis tance apart of the soc ets for the nuts. By

sockets is shifted to the position of the pro; ceding one, whereby they can be successivelv operated upon by the slotting tools as advanced. The present machine is shown procAs-rnLLa'rmc 'nurs.

vided with a driving shaft 10 that may receive its. power through a worm wheel 11 and worm 12 from a driving shaft 13, by which means the'shaft 10 is slowly rotated. This shaft is shown as provided with a segment gear 14 that engages a gear 15 fast a Suitablelocking means may be provided if. desired to retain the head in precisely the properposition each time it is thus advanced one-sixth of a revolution. The head isprovided'with six sockets 16, each of V which will be brought to register with a slidingbolt 17 after engagement of the segmer t 14 with the gear. Abent lever 18 pivoted-on a bracket 19 has one end engaging a socket 20 on the bolt 17; and the bolt is normally retained in locking position with the head by a spring 21. A disk 22 on the shaft 10 carries a roller 23 that at one position of the rotation will engage the extremity of thelever 18 and swing it to withdraw the bolt 17 and hold it out of en gagement with the socket portions 16 of the head; which roller is positioned relative to the segment gear 14 so that the bolt is with drawn and retained until the segment gear has advanced. the hcadthe unit distance, whereupon the bolt is released and will be drawn inward by the spring 21 to engage the socket and again lock the head.

.The nuts are fed downward by suitable means and inserted into the bushings after each advance of the head; A chute 24 is shown through which the nuts are fed downward by gravity and in their lowermost position therein will be opposite one of the sockets, the socket 9 as shown in Figs. 1 and 3.

A slide 25 is mounted on the bed 26 of the frame to move parallel with the axis of the head and is shown as operated by a roller 27 on the slide engaged alternately by diagonal straps 28 and 29 carried by the drum SO-fast on the shaft 10, by which means the silde is reciprocated intermittently once for each revolution of the shaft 10,'th e head being advanced one-sixth of a revolution by each straps sixty of sixty degrees with onel and sixty' degrees revolution of the shaft 10. Therefore the slide will move up and back once each time the head is indexed to advance the nuts in the bushings, The slide 25 carries m suit- 5 able bearings three vertical shafts 31, 32 and 33 having cutters 34, E35 and 36 respectively; and these cutters are located in axial alinement with the axeso'f the three socket members 9 that are in the uppermost positions,

10 as indicated in Figs. 1 and 3. Conseqii'ently.

when the slide is advanced the cutters will approach the socket members respectively, and they will engage the respective nuts that may be located or held therein. The cam 28 and, 29 are. so arranged that the slide will be advanced a sulticientdistance to cause theth'ree cutters'that are rotated by suitable, trieans, 'to inake' a diagonal cut or slot. inth'e nuts held in the sockets 9.

are each'rotatcd in a horizontal plane. Suitable-means. are provided for rotating these cutters, 'each 'of their shafts being provided with bevel enera, 38 and 3t) ineshing'with 25 bevel gears 40, 41 and 42 mounted on a shaft 43, horiioiitallysupported in the slide. This shaft is driven by suitable "means such as a car 44 ineshiiig with a fIQtII 45 on a stub shaft '46. The latter is shown as driven'by a pulley 47whieh may have an overhead helt' thereon, not shown. that will constantly drive it durin'g its horizontal reciprocation by the oilemcnt of the slide. By this means the chtters will be eonstantlydriven.

The nuts are fed in the position indicated by 9 in' Fig. 3. The. next advance of the head will liring this nut to the position 9. where it will be operated uponhy the first cutter and receive. a horizontal slot. The

40 next advance of the head w ll bring! this nut to the position 9. and as the nut has been given a circular movement of one-sixth of a revolution, the slot now out in it by the uppermost cutter will make an angle of degrees and obviously both of these slots will be iametral. The next advance of the head will bring the nut to the position 9 and the slot; .cut at thisposit on' will make an angle t e slot cut in the position 9 for the reason that'the. nut hasheen again'swung through an arc. of sixty degrees the"horizontal. Therefore the nut will nowbave received three slots that are diag- V apart, or in other words six radial slots will he cut in the face ofthenutI-Upon'a nut being fed in between eafeh advance of the head. and being suitably ejected after passing the position 9.

so it isevident that there are three slots cut at 24 upon the slide 25 being advanced, where- It. will be observed that the three cutters 'ith the slot previously out by this nut; will be shifted into the socket; 9, that is in registering position. The advance of the head will bring the three uppermost sockets adjacent a fan late 53 fast on red 54 'slidable in the head that is pivoted at the rear to a lever 57 swinging on a bracket 58. The lever 57 is connected with the machine by a spring 59 and presses a roller 60 against-a cam '61 on the shaft 10.. This cam normally engages the roller to position the fan plate 53 to hold the nuts in their sockets; the plate 53 being provided with slots 62, 63 and 64, through which the cutters respectively freely pass to engage the nuts that are held by the plate in their respective sockets. Thercupon the plate is released and drawn slightly back mit indexing of the head when the p ate again engages the nuts to lock them in the sockets.

To automatically eject the nuts, when in the position 9, suitable means are provided, comprising 'p'lu'ngers '65 mounted in sockets opposite each-ofhe bushings 9 and passing thereth'rough, these lungers being engaged by springs 66 to pro1ect slightlyto the rear, but having their forwardends not extend- -for the nuts.' As each of these reaches the position of the bushing 9' it engages a cam plate- 67 fast on the frame for the'head, and is thereby advanced against the pressure of its spring to engage and eject the nut held in the'bushing. As soon as the plunger leaves this position, itis dis-' normal position by the reaction of. its spring. By this construction it will be seen that the nuts are automatically fed from the chute into the, bushings. of the head, and when the head is advanced the bushing is carried upward, and the nut is engaged by the fan plate as soon as the head is again, arrested. In this position the nut has the first diagonal slot cut therein. During this operation the next nut is advanced into its bushing. At. thc'next, indexing of the head the first nut is advanced to the second position for slotting while the second nut is advanced to its first position-for slotting; and the third nut is now fed into the. bushing, The advancement of the cutters will cause the first not to receive the second slot: that is diagonal and at sixty first slot cut; While the second nut fed will dexing will bring the to receive its third slot that will be at sixty degrees to the second slot, whilethe second nut. will receive its second slot and the third nut its first slot. the fourth and? lacing now fed into the bushing. now have three slots that are diametral and sixty degrees separated, which is the same ing into the socket, portion of the bushing plungers engaged by the cam plate and returns to degrees with the receive its first slot, and the third nut-will be fed into a bushing. The next step of iii-*- first nut-into position by the spring to pe Thisefirst not will distance as six radial slots sixty degrees apart. The

next indexing will bring the first nut that has nowbeen entirely castellate'd to the position where it will be automatically ejected.
